If you add boiling water to a cup at room temperature, what would you expect the final equilibrium temperature of the unit to be? You will need to include 1he surroundings as pan of the system. Consider the zeroth law of thermodynamics.
Most automobiles have a coolant reservoir to catch radiator fluid than may overflow when 1he engine is hot. A radiator is made of copper and is filled to its 16.0L capacity when at 10.0C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0C operating temperature, given that the fluid’s volume coefficient of expansion is =400106/C ? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95.0C.
